Grind By Weight technology is now one of the most sought-after solutions for espresso preparation, both at home and in professional environments. Being able to set the desired coffee dose and have that exact amount delivered into the portafilter with a high degree of precision simplifies the barista’s workflow and makes it easier to replicate a recipe, dose after dose.

This is the concept behind the Mignon Stark W, the premium Grind By Weight grinder from Eureka ORO: a combination of advanced technology, highest quality of materials, power and control, designed for those who want maximum precision at every stage of the coffee preparation process.

Grind By Weight: The Dose You Want, Every Time

With Instant Grind Weighing Technology, users can set the desired dose directly on the display while the grinder continuously monitors the coffee weight during grinding.

On the Mignon Stark W, the system achieves an accuracy of ±0.2 g, delivering an extremely precise dose directly into the portafilter.

This means spending less time adjusting the dose and more time focusing on the elements that truly shape the final result in the cup: grind size, extraction time and recipe balance.

Accurate dosing also helps reduce coffee waste. Every gram can be used more efficiently, making it easier to get the most out of high-quality specialty coffees and premium blends.

Pure Diamond: Precision That Lasts

Grind By Weight technology is only one part of the Stark W experience. The quality of the grind starts with the burrs.

The Mignon Stark W is equipped with 65 mm Pure Diamond burrs, developed by Eureka and subjected to a special cryogenic treatment at -193°C.

This process is designed to enhance burr durability and contribute to consistent, reliable grinding performance over time.

Top Burr Without Screw Holes to reduce coffee retention

Another distinctive feature of the Stark W is the design of its upper burr, which features a screwless grinding surface.

By maximising the available grinding surface, this design promotes more direct contact between the burr and the coffee beans while helping to reduce coffee retention that can otherwise accumulate around screw holes and fixing points.

The result is a system designed to deliver precision, consistency and greater efficiency in dose management.

What else makes the Mignon Stark W Unique?

Stable Weighing with Anti Vibration System

The precision of the weighing system is supported by the Anti Vibration System, designed to maintain stable weight readings even if the grinder is accidentally touched or subjected to minor movements or vibrations.

This allows the system to continue operating with a high level of accuracy without compromising the selected dose.

Powerful motor and 65 mm Burrs

A high-performance motor works in combination with the 65 mm Pure Diamond burrs, allowing the grinder to process the coffee dose quickly and efficiently, including doses required for professional espresso preparation.

The combination of motor power and burr size delivers speed, consistency and control throughout the grinding process.

Universal Portafilter Fork

The Universal Fork is designed to offer broad compatibility with portafilters on the market.

It is compatible with most portafilters, including single, double and bottomless portafilters, making it easy to integrate the Stark W into different espresso setups.

King Size Grind Dial

Grind size adjustment is managed through the King Size Grind Dial, Eureka’s extra-large adjustment dial.

Its generous dimensions make adjustments more intuitive and precise, giving users greater control when searching for the ideal grind setting for their recipe.

High-Resolution Display

The high-resolution display provides intuitive access to the grinder’s main functions.

The dedicated submenu also offers a wide range of interface customization options, allowing users to personalize their experience according to their preferences.

10-Year Motor Warranty

A premium grinder is not only about performance. It is also about long-term reliability.

As part of our ongoing commitment to delivering long-lasting, high-performance products, Eureka offers a 10-year warranty on select motors, introduced in June 2025.

This initiative reflects Eureka’s confidence in the durability and engineering quality of its grinders.

Support Beyond the Purchase

Choosing a premium grinder means wanting maximum control not only during coffee preparation, but throughout the entire ownership experience.

That is why the Mignon Stark W features a QR code label on the side of the grinder, providing quick access to dedicated product content, including guides and video tutorials.

From setup and everyday use to system recalibration, these resources guide users step by step, helping them get the most out of the Stark W and enjoy a more confident coffee experience.

The Mignon Stark W is designed for those who want more than simply a specific dose of coffee.

It is a grinder for those who want the power to grind quickly, the technology to dose precisely and the control to fine-tune their recipe—and replicate it with consistency, shot after shot.
